Firewall behind the battery compartment (you checked there). Windshield seal, rear window seal. Sunroof drains. Hood hinge wells. The following are exerpts from emails I have in my archive on the subject... Rick Knoble '85 300 CD '87 190 DT Leo, There are numerous places that can leak both front and back. The sunroof is one of the least likely sources! In the front the windshield seal (usually rust under the seal is letting water in) the area of the hood hinges, the air inlet for the climate control system or the condensate drains (often the drain tubes are occluded or have rotted away) and rusting of the firewall under that battery tray are ALL sources for water to enter the cabin. The water WILL travel under the mats and end up in the rear footwells as that's the lowest spot in the car). Water CAN enter around the rear window (the rear package shelf is usually damp if this is the source) and migrate to the rear footwells also. To locate the source, remove the mats and have someone spray the car with a HEAVY spray while you stare at the underside of the dash with a powerful light source searching for water trails. Marshall -- Marshall Booth Rick, It can take a long time to get the water to dry in the foam backing of the carpets. Best thing is to let them soak in the sun for a few days. There are a number of ways for water to get in the car: bad windshield seal, clogged sunroof drains, rust thru behind the battery, clogged drains below the hood hinges, clogged air plenum drains on the firewall, and leaking evaporator drain tube are the usual. Wray Rick, My 1985 300D leaks through the firewall near the battery tray. To test for this, pull the mats and carpets up, and stick a garden hose such that water runs down the windshield on the passenger side. In my case, you can see it trickle down the inside of the firewall. I haven't attempted to fix it, mainly for lack of time; but I recall some postings about this very problem 2 or so years ago. Jim Thanks! Any recommendations for patching the rust holes if I can find them?
